RESUMO

El síndrome de linfocitosis infiltrativa difusa se produce en asociación con la infección por virus de la inmunodeficiencia humana; requiere cumplir con los criterios diagnósticos y descartar otras patologías infecciosas y autoinmunes. Se presenta el caso de una mujer de 47 años que consultó por edema parotídeo bilateral, síndrome sicca, tos y síndrome de impregnación. Se observó en la tomografía de tórax infiltrado en «vidrio esmerilado¼, parcheado y bilateral. Se realizó diagnóstico de virus de la inmunodeficiencia humana positivo y fibrobroncoscopia con lavado broncoalveolar sin desarrollo de patógenos. Se interpreta como neumonía intersticial linfoidea asociada a síndrome de linfocitosis infiltrativa difusa. Se inició terapia antirretroviral con buena evolución y desaparición de los síntomas y de los infiltrados pulmonares.


Diffuse infiltrative lymphocytosis syndrome occurs in association with HIV infection; it requires meeting the diagnostic criteria and ruling out other infectious and autoimmune pathologies. We present the case of a 47-year-old woman who consulted for bilateral parotid edema, sicca syndrome, cough and impregnation syndrome, which was observed in the chest tomography infiltrated in ground glass, patched and bilateral. A diagnosis of HIV positive and fiberoptic bronchoscopy with bronchoalveolar lavage was made without the development of pathogens. It is interpreted as lymphoid interstitial pneu monia associated with DILS. Antiretroviral therapy was started with good evolution and disappearance of symptoms and pulmonary infiltrates.

RESUMO

INTRODUCTION: There is scarce information about middle-term evolution of hospitalized patients who suffer from pneumonia caused by COVID-19. The objective of this study is to determine the clinical, respiratory, tomographic and functional impact on COVID-19 patients with moderate (MP) to severe (SP) pneumonia after six months of acute infection. METHODS: Analysis was carried out by MP and SP groups, desaturators during the 6-minute-walking test and the presence of fibrotic like pattern on HRCT. Outcomes at 3 and 6 months were compared. RESULTS: The analysis included 129 patients, between 57 ± 11 years old. Frequent comorbidities were: arterial hypertension 38.1%, diabetes 30.4%, respiratory 18.6%). Comparing 3 and 6 months, improvement in quality of life was observed in MP and SP. The DP walked less meters in the MWT, worsened life quality and more fibrotic like pattern. The fibrotic pattern was related to the fall of CVF < 80% on MP and SP (p = 0.048 and p = 0.007), and with DP (p = 0.002). On multivariated analysis, the fibrotic like pattern was associated to the reduction of CVF with OR = 4.44 (1.94-10.18, p <0.01) and desaturation OR = 5.01(1.63-15.42, p < 0.01). On this cohort it was observed more functional and tomographic compromise on the DP The fibrotic like pattern was related to worse functional evolution and oximetry. DISCUSSION: Follow-up after discharge of COVID-19 patients with SP, DP or fibrotic changes in HCRT is underlined.


Introducción: Hay información escasa sobre la evolución de los enfermos hospitalizados por neumonía por COVID-19 a mediano plazo. El objetivo de este estudio fue determinar en pacientes con neumonía moderada (NM) o grave (NG) por COVID-19, el impacto clínico, funcional respiratorio y tomográfico a los 6 meses. Métodos: Se realizó análisis según grupos de NM y NG, desaturadores (PD) en la prueba de caminata de 6 minutos y presencia del patrón tomográfico de alta resolución (TACAR) símil fibrótico. Se compararon los resultados a los 3 y 6 meses. Resultados: Se incluyeron 129 pacientes, edad 57 ± 11 años, comorbilidades frecuentes (hipertensión arterial 38.1%, diabetes 30.4% y respiratorias 18.6%). Al comparar 3 y 6 meses se observó mejoría de la calidad de vida en NM y NG. Los PD presentaron menor metraje caminado, peor calidad de vida y mayor presencia de patrón símil fibrótico. Este patrón se relacionó con la caída de la FVC 80% en NM y NG (p = 0.048 y p = 0.007), y con PD (p = 0.002). En el análisis multivariado, el patrón símil fibrótico s e asoció a la reducción de la CVF con OR = 4.44 (1.94-10.18, p <0.01) y a la desaturación, OR = 5.01 (1.63-15.42, p <0.01). En esta cohorte se observó mayor compromiso funcional y tomográfico en los PD. El patrón símil fibrótico se relacionó con peor evolución funcional y oximétrica. Discusión: Es importante el seguimiento de los pacientes con NG, los PD y los que presentan patrón fibrótico al alta de neumonía por COVID-19.

RESUMO

El tumor fibroso solitario de la pleura (TFSP) representa una neoplasia benigna de evolución habitualmente silente, hallazgo incidental y heterogeneidad en su presentación. Raramente se malignizan y la sintomatología se relaciona fundamentalmente con el compromiso por compresión de las estructuras vecinas. Su tratamiento es la cirugía. Se describe el caso de un paciente masculino de 49 años con antecedentes de hipertensión arterial, diabetes mellitus y obesidad que consultó al Servicio de urgencias por disnea. Se solicitó tomografía de tórax que evidenció voluminosa masa de densidad de partes blandas en hemitórax izquierdo con desplazamiento del mediastino y descenso del diafragma del mismo lado. La fibrobroncoscopia no evidenció lesión endoluminal. Fue evaluado por Cirugía del Tórax. Se realizó abordaje de la masa mediante toracotomía postero lateral izquierda. El estudio anatomopatológico informó formación tumoral de 25 × 16 × 13 cm, peso de 1905 gr y en la microscopía se describió proliferación celular fibroblástica, células fusiformes de núcleos pequeños ovoides y escaso citoplasma dispuestas en haces desordenados con colágeno interpuesto. La inmunohistoquímica informó vimentina y CD34 positivos. Se realizó el diagnóstico de tumor fibroso solitario de la pleura. La evolución posterior fue buena.


The solitary fibrous tumor of the pleura (SFTP) represents a benign neoplasm of commonly silent evolution, incidental finding and heterogeneous presentation. It rarely becomes malignant and symptoms mainly result from the involvement of neighboring structures due to compression. It is treated with surgery. We describe the case of a 49-year-old male patient with history of arterial hypertension, diabetes mellitus and obesity who consulted the Emergency Services because he was experiencing dyspnea. We requested chest tomography that showed a voluminous soft tissue density mass in the left hemithorax with mediastinal shift and decreased diaphragm on the same side. The fibrobronchoscopy didn't show endoluminal lesion. The patient was evaluated by the Thorax Surgery staff. The mass was treated by means of left posterolateral thorachotomy. The anatomopathological study reported the formation of a tumor of 25 × 16 ×13 cm and 1905 gr, and the microscopy described fibroblast cell proliferation, spindle cells of small ovoid nuclei and very little cytoplasm placed in disorganized bundles with collagen interposition. The immunohistochemistry disclosed positive vimentin and CD34. The patient was diagnosed with solitary fibrous tumor of the pleura, with good subsequent evolution.

RESUMO

The introduction of the anti-CD20 antibody rituximab into clinical practice has improved substantially the prognosis of a variety of haematological and autoimmune diseases. The interstitial lung disease is one of most serious and potentially fatal complications of rituximab therapy. This diagnosis should be considered in patients who have received the drug and present with dyspnea, fever and cough without clear evidence of infection. We report a case of rituximab-induced interstitial lung disease.

RESUMO

La introducción en la práctica clínica del anticuerpo anti-CD20 rituximab ha mejorado sustancialmente el pronóstico de diversas enfermedades autoinmunes y hematológicas. Con el incremento de su uso ha aumentado el registro de efectos adversos, entre ellos la toxicidad pulmonar. Una de sus complicaciones más serias es la enfermedad pulmonar intersticial, entidad potencialmente fatal que debe ser considerada en pacientes que han recibido rituximab y presentan disnea, fiebre y tos sin clara evidencia de infección. Presentamos un caso de enfermedad pulmonar intersticial asociada a rituximab.(AU)

RESUMO

BACKGROUND: Recently, the authors described a new variant of endemic pemphigus foliaceus in rural areas surrounding El Bagre, Colombia, but without association with malignant tumors. METHODS: The authors' 10-year fieldwork provided the opportunity to observe various manifestations of El Bagre endemic pemphigus foliaceus, including the presence of bilateral plaques in pretibial areas. RESULTS: Based on personal experience and literature reviews, the authors have correlated the auto-antibody profile with the appearance of pretibial plaques. CONCLUSION: Since pretibial plaques occur in patients with both fogo selvagem and El Bagre variants of endemic pemphigus foliaceus, as well as in other forms of pemphigoid, these diseases must be considered in the differential diagnosis of patients with clinical, immunologic, and/or epidemiologic risk factors.
